Unmissable in the skyline of Rome, the Gasometro is a welcome break from bustling Rome and serves as a contrast to its plethora of ancient monuments. This imposing structure is unique for it used to house Rome’s gas supply. With its name coined by William Murdoch, a Scottish engineer, the Gasometro is a structure designed in the early 20th century. Obsolete now for it no longer supplies gas to homes, it has thus become an industrial monument. Visible from Trastevere, a working-class district, this cylindrical structure is appealing in its own right and makes for an eye-catching picture.
